Should I lower my timings, or keep them the way they are?

post #1 of 14
Thread Starter 
I got Kingston Hyper X Ram 1333 MHz 4GB kit. The stock timings are 7-7-7-21, but my BIOS tells me 9-9-9-24. Should I change it, or keep it as it is? Is there much performance? My rig is in my sig. I also plan on OCing my CPU to somewhere around 4GHz

If the RAM is rated for 1333 @ 7-7-7-21, then thats what you should set it for in the BIOS. Your not using your RAM to its full potential.

You should notice a difference. Personally, lower timings yield slightly faster boot times and improved response when navigating Win7 and launching programs.

Yeah, I have some RAM at 1333MHz which is actually only rated for 9-9-9-24, but does 7-7-7-20 perfectly. Seeing as your RAM is actually rated for 7-7-7-21 that is what you should set it to in the BIOS. Like Baskt Case has said, you'll notice the difference in boot times and response in Windows.

Opening windows such as the control panel sped up when I lowered the timings.

I tried lowering timings to 7-7-7-21, I got a boot error and I would get a constant beep and I would get an OC error. I had my CPU Vcore at 1.35 at 4GHz, Dram at 1.64 and PLL at 1.14. Could it be the motherboard?

My bad, it is rated for 7-7-7-20. I'll try that now.

Did you just go straight from stock to 4GHz on the CPU?

7-7-7-20 would be harder to run than 7-7-7-21. Lower numbers = Lower timings = Harder to run.

What voltage is the RAM rated for? Make sure BIOS is set accordingly.

7-7-7-20 and 7-7-7-21 won't make a bit of difference. If it crashes @21 it will surely crash @20. Set the voltage to the recommended limit, if it's 1.64v try 1.65.

According to the Kingston site, http://www.kingston.com/hyperx/products/khx_ddr3.asp and KHX1333C7D3K2/4GDDR3-1333, unbuffered DIMM, my RAM is rated to run at 7-7-7-20 at 1.7 Volts. I know that anything over 1.65 will damage the CPU. Should I try, or is it not worth it? My mobo doesnt go to 1.65, its either 1.64 or 1.66.


EDIT: Should I only change Channel A timings, or B too? Sorry, I'm not familiar with RAM timings.

RAM Voltage has nothing to do with CPU Voltage. Two totally different areas of concern. Set your RAM voltage to 1.7v per the Kingston rating and try 7-7-7-21 again.

Change both A and B Channel Timings.

*Yes* it does. Intel chips IMC may be damaged by running higher than 1.65v RAM. 1.7v is not a good idea for long term use.

Just up loosen up timings some so it will run @ 1.65v and you will be fine. As the lower timings you will only see a difference in synthetic test. And it isn't going to make that huge of a difference either. Just run what is safe and be happy. You can always sell it and or purchase more ram as it is pretty cheap now.
